Plain-English answers from a contractor working in Brevard County every week.
$10,000-50,000+ depending on use case. Basic flex space/office: $10-20K. Bedroom + bath suite: $20-35K. Full ADU with kitchenette: $35-50K+.
Yes always. Brevard County requires building permit, plus electrical, plumbing, and HVAC permits depending on scope. We handle all permitting.
Yes if it meets code: minimum 70 sqft room size, egress window (or door) meeting code, proper ceiling height (7.5+ ft), HVAC, and electrical to code. We confirm code path during estimate.
Done right (preserves garage door aesthetic from exterior, professional finish work): typically neutral or slight positive impact. Done poorly (obvious conversion, no garage to sell to buyers who want one): can hurt resale 5-10% in some markets.
Yes. Either via the existing house, an exterior door cut into the new wall replacing the garage door, or a separate side entrance. Each has zoning implications - we check.
Depends on Brevard zoning for your specific property and HOA rules. Some Brevard zones allow ADUs with permits, some don't. We check zoning before quoting an ADU conversion.
4-10 weeks active construction depending on scope. Bedroom-only: 4-6 weeks. With bathroom: 6-8 weeks. ADU buildout: 8-12 weeks.
Mini-split ductless (cheapest at $2.5-5K), extend existing house HVAC (best aesthetics, $3-7K), or dedicated central air (independent control, $5-9K). Mini-split is most common for converted garages.
Florida code minimum is R-13 walls + R-30 ceiling. Garage conversions are often the worst-insulated part of the house when finished poorly. We always over-spec insulation slightly for comfort.
Inspect for cracks and moisture issues. Install a vapor barrier if needed. Then finish with LVP, engineered hardwood, or carpet. Slab leveling sometimes needed.
Yes - "partial conversion" preserves storage or workshop area. Half the garage becomes finished living, half stays utility. Common for homeowners who want both.
Two options: (1) frame in the opening with a real exterior wall (best long-term aesthetic), (2) keep the garage door but insulate/seal it for energy efficiency (cheaper, easier reversal). Most clients choose option 1.
Plumbing rough-in is the big variable. If existing house plumbing is nearby, $4-9K for a full bath. If we need to dig the slab for new plumbing, $6-12K. Half-bath simpler: $3-6K.
Yes - very common conversion in Brevard now. Office requires good lighting, cable/network drops, possibly soundproofing, and reliable HVAC. Cost: $10-25K depending on finish level.
Notify your carrier of the conversion - the square footage of living space changes, which affects premium. Usually a small premium increase. Garage conversions typically don't cause issues with insurance.
Brevard property tax may go up slightly because finished living space is taxed differently than garage. The county property appraiser usually catches converted space within 1-3 years.
Optional but recommended for ADU or in-law suite use. Adding sound insulation in the wall between converted space and main house: $800-2,500 depending on wall length.
Yes - popular conversion. Gym needs reinforced floor (epoxy or rubber over concrete), good ventilation, mirrors, and sometimes specialty electrical for equipment. Cost: $12-20K for nice gym buildout.
